Okay, so we've all heard of the many Fallout NV glitches. But strangely, I haven't had too many really noticeable ones, until this one. So I'm in Gomorrah, the dirty sex casino. And during one of the minor side-quests, you find out that one of the helpers is a sadist, and likes to kill women and make snuff tapes for pleasure. So, I killed him and took his closet key. Supposedly, when you get there, you find a dead prostitute corpse and if you examine it, you get additional information on it to appease another character of being charged with the crime. Well, when I opened the door, I was greeted by a live woman prostitute, walking around the room. I go up to talk to her, and the dialog says, "This woman is dead, do you wish to inspect her?" Next thing I know, she walks out the door and starts wondering around the casino.
This just struck me as really creepy, it's like the corpse came back to life and walked around. I know it's just an object-oriented glitch in the programming. Somehow, the program decided that the girl is supposed to be alive instead of dead. But still, it creeps me out.
